Dr Keating Email Interview, page-104

Or how about this;

(i) Patient is presumed clear of infection from initial consultation (tele-health or in person) based on other products / existing approaches. (told it is a flu or cold)
(ii) Condition of the patient deteriorates
(iii) Patient knows that something isn't right downloads Resapp onto their phone for $10
(iv) Patient runs test and app advises that they have X
(v) Patient presents to ER/Doctor and shows them the result, ER/Doctor confirm diagnosis and treat patient. (If same Doctor then patient tells doctor that they think they are wrong......(Maybe doctor sees value of app as well)
(v) Patient now realises that App is better than Doctor and now when they are feeling unwell purchases another test from App. Patient now uses App to see if they should go to doctor.
(vi) Doctor loses income from Patient. Resapp gains income from patient.

Somewhere a butterfly's wings flap.....
